Coolants > APEX 6420
Description
APEX 6420 is a light to moderate duty synthetic coolant. It has superior oil rejecting capabilities. Formulated for use in grinding applications and light duty machining. APEX 6420 runs very clean and is low foaming in hard and soft water applications. Works well in both ferrous and most nonferrous applications.
Advantages
- GOOD RUST AND CORROSION PROTECTION ON FERROUS
AND MOST NONFERROUS METALS - EXCELLENT STABILITY IN HARD AND SOFT WATER APPLICATIONS TO ENSURE
MINIMAL RESIDUE BUILD-UP - QUICKLY REJECTS TRAMP OILS TO THE SURFACE
- LOW FOAMING IN ALL WATER CONDITIONS
- PREVENTS BIMETALLIC CORROSION AND IS SAFE TO USE IN EQUIPMENT
WITH MOST COPPER, BRASS, BRONZE, AND ALUMINUM COMPONENTS
